The above is just some warn logs, are there more logs?

[imhun]

no more logs,upgrade is stuck because the pvc check failed
it should ignore this error,because the old version tikv pod was already running
it should check it when create new pod instead of checking what already exists

[csuzhangxc]

but the continue wouldn't block reconciliation,
